Gantry surface grinder P2060
1.High rigidity/regrinding:
Surface/contour/surface forming grinding
2.Machine tool characteristics:
High rigidity structure
The fuselage is designed as an integrated double V track structure.
All the castings are made of high-grade cast iron, which is
annealed and aged to eliminate the internal stress. The box body is
equipped with reinforced ribs to enhance the structural rigidity.
Lubrication system
The high precision lubrication system makes the machine run more
stable and can withstand regrinding. The precision feed system
greatly improves the grinding efficiency.
Worktable
Table moving back and forth (X axis) slide rail, using double V
structure design, continuous forced lubrication, avoid wear, high
motion accuracy, high service life.
Ball screw
The machine adopts C3 precision ball screw, which is directly
driven by servomotor.
3.Precision spindle:
The main shaft of the grinding wheel is made of nickel-chromium
alloy steel, and the internal stress is eliminated through heat
treatment, precision grinding and dynamic balance correction.
The grinding wheel mandrel adopts dynamic pressure composite
lubrication design, which is easy to form a higher oil film
supporting pressure. When it is lower than the working pressure,
the automatic pressure detection switch will prevent the start of
the abrasive wheel shaft to avoid the mutual wear between the
mandrel and the copper bearing shaft. Moreover, the lubricating oil
temperature control cooling device is attached to avoid the oil
viscosity decreasing due to high temperature, thus affecting the
maintenance of pressure.
Device description:
1. The body and components are cast by Milhanna high grade cast
iron FC30, which is artificially normalized heat treatment and then
treated by natural aging. Components are processed by YASDA, MITSUI
SEIKI, TOSHIBA, ELB and other world-class equipment once clamping
processing. Precision size can be up to micron level, to ensure
high precision equipment basic components.
2. Machine guide rails and precision ball screws are continuously
lubricated by automatic lubrication system to ensure longer service
life and accuracy. The cooling system is separated from the body to
eliminate vibration and favorable heat dissipation.
3.Equipped with Siemens 828D CNC automatic grinding system, and
secondary development, man-machine dialogue fool operation, with
many optional equipment to choose from, including inner hole
grinding device, automatic end measuring device, automatic outside
diameter measuring device, etc.
4. The grinding feed system is composed of a V and a flat track of
hand-crafted precision shovel, with automatic lubrication system
and C3 level precision grinding ball screw, which can achieve
smooth movement, excellent repeated positioning accuracy and long
track life.
5. The standard configuration of the grinding wheel spindle is rear
four and rear two bearing structure. High precision dynamic and
static pressure spindle can also be selected, which has the
characteristics of high rotation precision, high dynamic stiffness,
good vibration resistance, high grinding efficiency and good
grinding surface quality. For special work-piece grinding, the
grinding wheel speed can be adjusted, up to 3500 RPM and 60m/s.
6. The tail seat is designed to be both rigid and robust. A
hardened alloy steel sliding cylinder encrusted in the cast iron
body is designed to carry the MT4 top core. The jacking force of
the sliding cylinder can be easily changed by adjustment knobs at
the rear. Special accessories oil pressure tail seat with a pedal
to facilitate unloading work parts.
7.Siemens numerical control system as the standard configuration,
after secondary development, all Chinese operation interface, easy
to use. Equipped with Siemens high performance servo motor, the
equipment CNC system and drive system have better compatibility, at
the same time with automatic sand repair and automatic compensation
function, to ensure the stability and precision of feed and
grinding.
